Concept Search - What can I type?

For a concept search, you can enter phrases, sentences, or full paragraphs in English. For example, copy and paste the abstract of a patent application or paragraphs from an article.

Concept search eliminates the need for complex Boolean syntax to inform retrieval. Our Semantic Gist engine uses advanced cognitive semantic analysis to extract the meaning of data. This reduces the chances of missing valuable information, that may result from traditional keyword searching.

Buoyancy Enhanced Offshore Structures

Abstract

Construction of offshore structures requires significant mass to ensure that they can withstand loads produced by wind and waves. Offshore structures in the Arctic require additional mass to resist loads produced by ice flows. The amount of metal and / or concrete required for offshore structures to resist wind / wave / ice loads adds significant cost and construction time for offshore projects.

Offshore structures in the Arctic require additional mass to resist
loads produced by ice flows. The amount
of metal and / or concrete required for offshore structures to resist wind /
wave / ice loads adds significant cost and construction time for offshore
projects.

Concept Description

Water
buoyancy is used to add weight to offshore structures. This is done by placing buoyancy cans /
balloons under water and connecting them to lever arms. The lever arms are then connected to the
offshore structure – see Figure 1 below (Figure 2 shows an alternative that uses underwater thrusters to produce a lever-arm
enhanced force in the desired direction).

The concept
can provide additional downward force (weight) for any type of offshore
structure. This could be an important
enabler for ice-prone structures but it could also have value for open water
applications by minimizing the size of the fabricated structure.
